This was a really good book. I thought at first that it would be a story from the "mistress" side of a relationship, but oh how wrong I was. I felt deceived, but it was a great feeling of deception once I learned exactly what was going on. I can usually predict most things that I read, but this one definitely got me and kept me going until the end and even the ending left my mouth hanging wide open. There was so much to expect and not expect. I loved it.
